Sex and Significance
How the Heritage Foundation cooked the books on virginity.
But Brückner and Bearman aren't campaigning. They don't try, for example, to hide the finding that virginity pledges delay and decrease nonmarital intercourse; they even wrote a long paper in 2000 on the contexts in which pledges are most effective. They're not sneering libertines lobbing condoms over the walls of your daughter's virtue; they're scientists, doing their jobs. Rector and Johnson are spinners, doing theirs. If you want to study a significant difference, look no further.
